Jun 2026

Summary

Behavioral round at Uber for a software engineering role, basically one big question about your best project dressed up with six sub-parts. Not a bad experience but it felt more like a structured debrief than a real conversation.

Questions Asked (1)

Q1

Walk me through the most impressive project you've worked on, covering the business problem, your role, the technical decisions you made, how you measured success, the hardest challenge you faced, and what you'd change if you did it over.

Suggested Approach

Choose a project where you drove significant business impact through technical decisions, and structure your answer as a narrative that connects the problem, your actions, and measurable outcomes. Emphasize trade-offs you evaluated and how you validated success with data, while being honest about challenges and learnings.

Pro tip: Quantify impact in terms of Uber's key metrics (e.g., trips, ETAs, driver utilization) and show how your technical choices directly moved those numbers. Also, briefly mention how you collaborated with product, data science, or operations teams to ensure alignment.

1. Set the Context and Business Problem

Briefly describe the project's goal, why it mattered to Uber's business, and the scale (e.g., number of users, trips, or revenue impacted). Avoid deep technical details here; focus on the 'why'.

2. Define Your Role and Technical Decisions

Clarify your specific responsibilities and the key technical choices you made. Explain the alternatives you considered and why you chose your approach, highlighting trade-offs (e.g., latency vs. cost, consistency vs. availability).

3. Explain How You Measured Success

Describe the metrics you used to evaluate the project's success (e.g., reduced latency, increased conversion, cost savings) and how you tracked them. Mention any A/B tests, dashboards, or experiments you ran.

4. Discuss the Hardest Challenge and Resolution

Pick a genuine technical or organizational challenge you faced, explain why it was difficult, and how you overcame it. Show problem-solving and resilience.

5. Reflect on What You'd Change

Share what you learned and what you would do differently next time, demonstrating self-awareness and growth mindset. Tie it back to how it improved your subsequent work.

Key Points to Mention

  • Quantifiable business impact (e.g., increased trips by X%, reduced ETA by Y seconds, saved $Z in infrastructure costs)
  • Technical trade-offs (e.g., choosing between microservices vs. monolith, SQL vs. NoSQL, caching strategies)
  • System design considerations (e.g., scalability, fault tolerance, data consistency)
  • Metrics and measurement (e.g., A/B testing, key performance indicators, monitoring)
  • Collaboration with cross-functional teams (e.g., product managers, data scientists, operations)
  • Lessons learned and how you applied them to future projects
